It's never too late to make a positive change in your life. If the marriage is making you miserable then get out of it. I've been married once, divorced for eight years, and I don't plan on doing it again. Some guys think they have to be married to be happy, I'm here to tell you that you don't. You're not feeling well about your situation right now but I'm here to tell you that things can and WILL get better. It's temporary and there is plenty of time to find a good life that you enjoy waking up to every morning. Find someone local to talk things out with first, a pastor is a good choice. I don't know if you have one or not but I've never met one who wouldn't willingly invite someone who asked for help into their home to talk over coffee. If you don't know one then ask some older lady nearby who their pastor is, she'll be happy to put you in touch.
